Description: Approaches to the management by the multiprojects of creation of sophisticated technical system (SТS) are considered, allowing to abbreviate terms and cost of development of such systems. The model of stage of the external planning STS is built, based on principles of customizations and reverse planning. The methods of acceptance of decisions in a process structurally are structural-parametric synthesis STS. The critical analysis of methods is conducted. Perspective directions of researches are set.
Keywords: multiproject, sophisticated technical system, decision-making method, structural-parametric synthesis, genetic algorithm, fuzzy logic, methods of morphological analysis
